Hi Guys, This is some great software you have here and I commend you for the great effort that has gone into it! I have a question about how to address the answers from the following example: I tried addressing it as a vector, but it is a scaler so this will not work. Thanks in advance, Daniel

Hello Daniel Daniel wrote:I have a question about how to address the answers from the following example: I tried addressing it as a vector, but it is a scaler so this will not work The Equation systems template should, actually, give a vector. Try this: x←10±5x=sys(15;5;2;1)el(x;1;1)=15el(x;2;1)=5As this is a vector you can omit the second index BTW, it seems there are some problems with Equation system.

Ahh I see, I was trying to access this using the matrix minor function thinking it was the same as what the key "[" provides (which I only just figured out too!). I could not find a reference to access matrix elements in your SMath tutorial, but did find it here: http://en.smath.info/for...t.aspx?g=posts&t=138

Nice to see vectors with single subscripts. Was a literal subscript (in Mathcad its the {.}) implemented? Also, do all matrix/array/vectors start at 1? In Mathcad the Origin defaults to "0". Either way is fine.

Hello ElSid ElSid wrote:Nice to see vectors with single subscripts. Was a literal subscript (in Mathcad its the {.}) implemented? Also, do all matrix/array/vectors start at 1? In Mathcad the Origin defaults to "0". Either way is fine. As I remember, few posts mentioned literal subscript. You are right, we (Mathcad users) are used to literal index notation. I think this is not implemented. The final decission is on SMath creators. Also, we are used to ORIGIN in Mathcad. As I remember, ORIGIN made problems in earlier version of Mathcad. I agree with you, starting index at 0 or 1 makes no difference, as far as I am concerned. In my experience, the only use of ORIGIN was to set it up to 0 or 1. I do not remember that I set it up to some other values. Regards, Radovan Edited by user 06 October 2009 02:24:16(UTC)

Just curious to know which way the developer goes. Mathcad defaults to ORIGIN=0. For most people, ORIGIN=1 is initially easier, although thinking of an initial state (velocity sub initial) is typically written with 0
